What Are Deductible "Investment" Expenses?

In general, expenses related to the production of taxable investment income are deductible as miscellaneous itemized deductions subject to the 2% of AGI limitation.

These would include investment advice fees, publications, brokerage fees (if for purchase or sale of securities, these are instead considered part of the tax basis of the security), software for
investment tracking, pro-rated costs of a computer used for investments purposes (See separate FAQ regarding computers), online service charges incurred for investment advice access, postage and
telephone charges regarding investments, etc.
